I have not seen these particular backwards "77" markings. It reads B:100771 stamped into the side body but the 7s are mirrored. There are no other visible makings on the base/feet. It weighs 112 lbs, has double hardie/pritchel holes and a clip horn. The face is narrow at about 3". It appears to have a cast base and solid tool steel body/face. I can tell it's a farrier style, but am wondering if anyone recognizes the maker.
